Description

Technical Field

[0001] The invention belongs to the technical field of maglev tracks, and in particular relates to an inner mold component, a molding system and a molding method of a maglev track beam molding system. Background Art

[0002] Magnetic levitation technology uses magnets to generate lift and thrust, allowing the vehicle to float very close to the "guide rail". Since there is no friction from physical contact, most of the power is used to overcome air resistance. In terms of operating energy consumption, high-speed maglev has obvious advantages over high-speed railways.

[0003] The track beam of the maglev train is the basis for the operation of high-speed maglev trains. The track beam is a high-precision component in the maglev track structure system. In high-speed maglev technology, since the suspension height and guide clearance of high-speed maglev trains are only 8-10mm, the construction quality and installation quality of the track are extremely high.

[0004] Maglev track beams are divided into straight beams, curved beams and space curved beams according to their line shape. In addition to being an arc with a certain radius of curvature on the horizontal plane, the space curved beam is also curved in the Z direction. Due to its structural characteristics and requirements on processing accuracy, it further brings great difficulties to the processing and assembly of the space curved beam. Summary of the invention

[0005] The purpose of the present invention is to provide a maglev track beam, a maglev track beam forming system and a forming method, so as to solve the problems existing in the processing of the maglev track beam.

[0006] The present invention is achieved through the following technical solutions:

[0007] The inner mold assembly of the maglev track beam forming system includes two inner templates hingedly connected at one end, the two inner templates are arranged opposite to each other, the other ends of the inner templates are respectively connected to the base through hinged connecting rods, and the two ends of the hinged connecting rods are respectively hinged to the inner templates and the base. When the maglev track beam is hoisted and demoulded from the forming system, the inner template can move upward in the vertical direction with the maglev track beam and move inward relatively under the action of the hinged connecting rod.

[0008] In some embodiments, a reset component is also included, which is used to enable the inner mold component to return to the state and position of the inner mold component during casting under the action of its own gravity after the maglev track beam is hoisted and demolded from the molding system.

[0009] In some embodiments, the reset assembly includes at least two positioning pins arranged at positions on the bottom mold assembly corresponding to the two inner templates, the positioning ends of the positioning pins are conical structures, and positioning holes cooperating with the positioning pins are respectively arranged at the ends of the two inner templates, and the positioning holes are conical structures cooperating with the positioning ends of the positioning pins.

[0010] In some embodiments, during casting, the inner formwork and the bottom formwork assembly are fixedly connected by bolts.

[0011] In some embodiments, a first sealing strip is provided at a hinged position of the two inner templates.

[0012] In some embodiments, it also includes two inner end templates respectively arranged at both ends of the inner template, and the inner end templates are movably connected to the inner template so that the inner end templates can move with the maglev track beam and separate from the inner template when the mold is opened.

[0013] In some embodiments, hook heads are respectively provided at both ends of the inner template, and matching hook grooves are provided at corresponding positions on the inner end template. The inner end template is connected to the inner template through the hook groove and the hook head.

[0014] In some embodiments, the upper end of the inner end template is inclined relative to the vertical plane toward the inner side template.

[0015] In some embodiments, a second sealing strip is provided between the inner end template and the inner side template.

[0016] On the other hand, the present invention also provides a maglev track beam forming system, comprising:

[0017] Inner mold components; and

[0018] A bottom mold assembly, which is arranged on a base and includes a beam bottom mold and support bottom molds located at both ends of the beam bottom mold;

[0019] A side mold assembly, the side mold assembly comprising two side mold plates arranged opposite to each other;

[0020] The end mold assembly includes two end mold plates arranged at both ends of the side mold assembly and two support end mold plates located at both ends of the beam bottom mold.

[0021] On the other hand, the present invention also provides a method for forming a magnetic levitation track beam, comprising the following steps:

[0022] Close the mold and fix the two inner molds to the bottom mold assembly by bolts;

[0023] After pouring is completed, the mold is opened, and after removing the bolts between the inner mold and the bottom mold assembly, the formed maglev track beam is hoisted and demoulded from the forming system.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] 1) The present invention designs the inner mold component of the molding system according to the structural characteristics of the beam body of the maglev track beam. While realizing the molding of the π-shaped maglev track beam, the demoulding operation between the maglev track beam and the inner mold component is convenient, and the method adopted in the demoulding operation can be used to realize passive demoulding between the inner mold component and the maglev track beam. In this way, there is no need to set up an additional driving mechanism to demould the inner mold component during the demoulding operation, which simplifies the structure of the entire molding system and facilitates the arrangement of the inner mold component in the molding system.

[0026] 2) During the demolding process of the inner mold assembly of the present invention, the inner mold plate can move with the maglev track beam and separate from the maglev track beam in the lateral direction during the process, thereby avoiding interference between the inner mold plate and the maglev track beam during demolding, and ensuring smooth demolding between the maglev track beam and the inner mold assembly in this passive demolding operation.

[0027] 3) In the inner mold assembly of the present invention, the inner end template and the inner side template are movably connected. When demoulding, the inner end template and the inner side template can be separated, thereby facilitating demoulding of the inner mold assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0055] The present invention is used for forming the magnetic levitation track beam, referring to Figure 1 The maglev track beam 10 includes a beam body 11 and supports 12 located at both ends of the beam body. The beam body 11 and the supports 12 are integrally cast by concrete, wherein the cross section of the beam body 11 is a π-shaped structure.

[0056] In order to form a beam body with a π-shaped structure, the present invention sets an inner mold assembly in the molding system, which cooperates with the molding system for molding the beam body and the maglev track beam. At the same time, it is also necessary to consider the demolding operation of the maglev track beam and the molding system, the inner mold assembly and the maglev track beam after molding.

[0057] The following combination is used for molding Figure 1 The structure of the magnetic levitation track beam forming system used by the magnetic levitation track beam shown in the figure explains the structural characteristics of its inner mold component.

[0058] In some embodiments, reference Figure 3 and Figure 4 The maglev track beam forming system usually includes a bottom mold assembly, a side mold assembly, an end mold assembly and an inner mold assembly.

[0059] The bottom mold assembly is arranged on the base 21, and includes a beam body bottom mold 221 for forming the beam body part and a support bottom mold 222 located at both ends of the beam body bottom mold for forming supports at both ends.

[0060] The side mold assembly includes two side mold plates 241 arranged opposite to each other on both sides of the bottom mold assembly.

[0061] The end mold assembly includes two end mold plates 251 arranged at both ends of the side mold assembly and two support end mold plates 26 located at both ends of the beam body bottom mold for forming the inner end surfaces of the two supports.

[0062] The inner mold assembly is arranged on the base 21 and is located at a position corresponding to the bottom mold of the beam body.

[0063] When the bottom mold assembly, the side mold assembly, the end mold assembly and the inner mold assembly are closed, a molding space for molding the maglev track beam is formed inside.

[0064] In some embodiments, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The inner mold assembly 28 includes two inner templates 281 hingedly connected at one end, and the two inner templates 281 are arranged opposite to each other. The other ends of the inner templates 281 are respectively connected to the base 21 through hinged connecting rods 282. One end of the hinged connecting rod 282 is respectively hinged to the lower ends of the two inner templates 281, and the other end is respectively hinged to the hinged supports 283 arranged on the base. When the maglev track beam is hoisted and demoulded from the molding system, the inner template can move upward in the vertical direction with the maglev track beam. At this time, the hinged connecting rod connected between the inner template and the base applies an inward force to the inner template, so that the inner template moves inward relatively. At this time, the inner template is separated from the inner side surface of the maglev track beam, thereby facilitating the demoulding between the maglev track beam and the inner mold assembly.

[0065] In some embodiments, the inner mold assembly includes a reset assembly, which is used to enable the inner template to return to the state and position when the molding system is closed under the action of its own gravity after the maglev track beam is demolded, thereby realizing automatic reset of the inner template, so as to facilitate the use of the molding system and continuous molding operations, reduce the labor intensity during molding operations, and make the molding system have better practical performance.

[0066] In some embodiments, the reset assembly includes at least two positioning pins 284 arranged at positions on the bottom mold assembly corresponding to the two inner molds. Specifically, the positioning pins 284 are arranged on the beam body bottom mold 221 of the bottom mold assembly, and the positioning end of the positioning pin 284 is set to a conical structure. Positioning holes 285 that cooperate with the positioning pins are respectively provided at the ends of the two inner molds, and the positioning holes 285 are conical structures that cooperate with the positioning ends of the positioning pins.

[0067] In the initial state, the inner mold assembly is positioned and installed on the bottom mold of the beam body through the positioning holes 285 set thereon and the positioning pins 284 set on the bottom mold of the beam body, and the positioning pins limit the position of the inner mold on the bottom mold of the beam body. After the casting is completed, the maglev track beam is hoisted and demoulded from the molding system. When the inner mold moves upward along the vertical direction with the maglev track beam and moves relatively inward under the action of the hinged connecting rod, the setting of the conical matching structure provides a certain activity space for the inner mold to move inward relative to each other. When the inner mold is separated from the beam body and completely demoulded, under the action of the inner mold's own gravity, the inner mold falls back to the position where the positioning pin is located through the guiding action of the positioning pin, and the repeated positioning of the inner mold is achieved through the positioning pin.

[0068] Based on the above-mentioned reset principle, the reset component here can also be adopted by controlling the opening angle of the two hinged links in the initial state, so that when the inner formwork is separated from the beam body and demolded, the hinged link is opened and restored to the initial state under the action of the inner formwork's own gravity. At this time, since the opening angle of the hinged link in the initial state is limited, the inner formwork can be restored to the state and position during casting.

[0069] In some embodiments, when the maglev track beam is cast and formed, after the molding system is molded, in order to ensure the stability of the position of the inner mold assembly, the lower end of the inner mold 281 can be fixedly connected to the beam body bottom mold 221 of the bottom mold assembly by bolts.

[0070] During the demoulding operation, the bolts between the inner template 281 and the beam bottom template 221 need to be removed first.

[0071] In some embodiments, a first sealing strip 286 is provided at the hinge position of the two inner templates. The first sealing strip 286 is provided on the inner side of the inner template and along the longitudinal direction of the inner template, and is used to seal the gap formed at the hinge position of the two inner templates to ensure the molding quality of the beam body.

[0072] against Figure 1 and Figure 2 The structural features of the maglev track beam shown in the figure are that since the inner mold assembly only needs to mold the internal space at the beam body position, it is necessary to close the two ends of the two inner templates. In some embodiments, the inner mold assembly also includes two inner end templates 287 respectively arranged at the two ends of the inner template. The inner end template 287 closes the two ends of the inner template 281. At this time, a relatively closed space is formed between the inner end templates and the inner templates, which is used to mold the hollow internal space at the beam body position in the molding system; the inner end templates and the inner templates are movably connected, so that the inner end template can move with the maglev track beam and separate from the inner template when the mold is opened.

[0073] In this way, during the demoulding operation, the inner end template can be separated from the inner side template to facilitate the demoulding operation between the inner mold assembly and the maglev track beam, and to a certain extent avoid the restriction of the inner end template on the movement of the inner side template.

[0074] In some embodiments, to achieve the above functions, Fig.10 and Fig.11 Two hooks 2881 are respectively arranged at the ends of the inner template, and the hooks 2881 are arranged upwards. Four matching hook grooves 2882 are arranged at the corresponding positions on the inner end template, and the openings of the hook grooves 2882 are arranged downwards. The inner end template is connected to the inner template through the hook grooves and hooks. When the maglev track beam is hoisted and demoulded from the forming system, the end mold is hoisted out of the forming system with the maglev track beam, and the inner end template is removed from the maglev track beam and reinstalled on the inner template, and the cycle operation of the next beam can be carried out.

[0075] It is easy to think that a hook groove with an upward opening can also be provided on the inner template, and a hook head facing downward can be provided on the inner end template. In this case, a movable connection between the inner end template and the inner template can also be achieved.

[0076] In some embodiments, Fig.10 The inner end template 287 is set to have a certain inclination angle, so that a certain demoulding angle α is formed between the inner mold assembly and the maglev track beam. Specifically, the upper end of the inner end template is inclined relative to the vertical plane toward the inner side template to facilitate the demoulding operation between the inner mold assembly and the maglev track beam. The inclination angle of the inner end template, that is, the demoulding slope, can be set as needed.

[0077] A second sealing strip 289 is provided between the inner end template 287 and the inner side template 281 to seal the gap therebetween, so as to ensure the molding quality of the maglev track beam.

[0078] In some embodiments, the molding system also includes two sets of side mold bases 242 arranged relatively to each other, the side mold bases 241 are respectively arranged on the side mold bases 242 and are slidably connected with the side mold bases, and a side mold driving component 243 is arranged between the side mold bases 242 and the side mold bases. The side mold driving component 243 is used to drive the side mold base to move along the lateral direction of the maglev track beam to realize the closing and opening operations of the side mold base.

[0079] A slide rail 244 is provided on the side mold base 242, and the guide surface of the slide rail is gradually inclined downward toward the outside along the transverse direction of the magnetic levitation track beam. A slider 245 that cooperates with the slide rail is provided on the side mold plate 241. The slider 245 is provided on the slide rail 244 so that when the slider moves away from the track beam on the slide rail, the side mold plate can move downward at the same time. The guide surface of the slide rail is set as an inclined structure. When the side mold plate is demoulded, the side mold plate moves outward and downward at the same time, which can effectively prevent the interference between the functional component mold plate 27 set on the side mold plate and the cast magnetic levitation track beam.

[0080] In some embodiments, an end mold base 252 is respectively provided at the position where the end mold plate 251 is located, and one end of the end mold plate 251 is provided on the end mold base 252 and is connected to the end mold base 252 through a pivot sliding fit, so that the end mold plate can rotate around the pivot on the end mold base and slide in a horizontal direction on the end mold base.

[0081] The molding system further comprises an end mold driving assembly, which comprises a first end mold driving member 253 and a second end mold driving member 254, for driving the end mold plate to slide and rotate on the end mold base.

[0082] By setting the end template to be connected to the end template base through a pivot rotation and also able to slide on the end template base, during the demoulding operation, the end template can first move outward and separate from the end surface of the maglev track beam, and then flip the end template to achieve demoulding of the end template. Fig.16 This can solve the problem that the end template is easily interfered with the magnetic levitation track beam when opening the mold because the end template is provided with a hole template for forming the end face beam hole on the end face of the track beam.

[0083] In some embodiments, the first end mold driving member 253 is connected to the end mold plate 251 at a position close to the end mold base 252, and the second end mold driving member 254 is connected to the end mold plate 251 at a position away from the end mold plate base 252. In this way, when the end mold plate is demoulded, the first end mold driving member first drives the end mold plate to move horizontally outward to separate the end mold plate from the maglev track beam, and then the second end mold driving member flips the end mold plate.

[0084] End mold support bases 255 are respectively arranged on the outer sides of the end mold plates 251 for supporting the demoulding end mold plates.

[0085] Entrance channels 211 for convenient access are respectively arranged on both sides of the base 21 , so that operators can enter the forming system conveniently, thereby facilitating operations during the forming process of the track beam.

[0086] The above-mentioned inner mold assembly and molding system can also be applied to the molding of magnetic levitation track beams with different transverse slope angles. Only one set of molding mold system is used to realize the processing and molding of track beams with different transverse slope angles.

[0087] In the above embodiment, the side mold driving member can be provided in plurality, and the plurality of side mold driving members are distributed and arranged along the longitudinal direction of the side mold plate. Among them, the side mold driving member, the first end mold driving member, and the second end mold driving member can adopt hydraulic cylinders.

[0088] Specifically, the bottom surface of the beam body of the maglev track beam 10 is arranged to be suspended and located above the bottom surface of the support, and the outer contour line of the cross section of the toe 13 of the support is arranged to be an arc shape.

[0089] Accordingly, the support bottom mold 222 in the bottom mold assembly is configured to be rotatable around the central axis of the bottom surface of the base, such as Fig.12 and Fig.15 As shown, the forming requirements of the magnetic levitation track beam with different transverse slope angles can be adapted by adjusting the inclination angle of the support bottom mold.

[0090] In the side mold assembly, the cross section at the toe position of the magnetic levitation track beam on the side mold is set to be an arc shape. In this way, the rotatable support bottom mold and the side mold are matched, so that the support bottom mold can be rotated and adjusted to any desired inclination angle.

[0091] In this way, when the maglev track beam is formed, the inclination angle of the support bottom mold can be flexibly adjusted according to the different inclination angles of the support bottom surface, so that the maglev track beam with different inclination angles of the support bottom surface can be formed by a set of forming systems. Figure 1 , Figure 2 , Fig.13 and Fig.14 , which are schematic diagrams of the structure of the maglev track beam when the transverse slope angle is 0° and 12° respectively.

[0092] On the other hand, the present invention also provides a method for forming a magnetic levitation track beam, comprising the following steps:

[0093] Adjust the support bottom mold to the same angle as the bottom surface of the formed maglev track beam support;

[0094] The side mold assembly and the end mold assembly are closed, and the two inner molds are fixedly connected to the bottom mold assembly by bolts;

[0095] After the pouring is completed, the two end templates are demoulded to the two ends, the connection between the functional part template and the magnetic levitation functional part is removed, and the functional part template is demoulded, and then the side templates on both sides are slid to the two sides for demoulding, and after the bolts between the inner template and the bottom template assembly are removed, the formed magnetic levitation track beam is hoisted and demoulded from the forming system;

[0096] Remove the inner end template left on the maglev track beam, reconnect the inner end template to the end of the inner side template, and then proceed to the forming operation of the next beam.

[0097] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship commonly placed when the product of the invention is used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0098] In addition, if the terms "horizontal" or "vertical" appear in the description of the present invention, it does not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0099] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
